[SOLVED]Attributes tab won't show on new products page

[Susi]

I'm sorry if this is a duplicated topic but I couldn't find anything like this.

I just added a new attribute group, filled up with attributes and then try to create a new product but... there's no "attribute tab" there. I only have product and images tabs.

I installed a spanish translation and though that was the problem... so I unistalled but no, I still cannot see atts. tab.

Any ideas?

Thank you in advance!

PS. I haven't modify anything in my back office codes, just in the front and nothing to do with modules, just design.
Thanks!

You must enter the product information and save the product before all the tabs appear.
